Nonstationary time series are frequently detrended in empirical investigations by regressing the series on time or a function of time. The effects of the detrending on the tests for causal ...

Granger causality can estimate the direction, strength and frequency of information flow among the recording sites. In the future, the research team would like to make the computer program faster and ...

Mapping causality in neuronal activity: New method uses spike train data to identify connections
Understanding the brain's functional architecture is a fundamental challenge in neuroscience. The connections between neurons ultimately dictate how information is processed, transmitted, stored, and ...
